AERONAUTICAL APPARATUS.

Specification of Letters Patent.

Application filed October 10, 1916. Serial 110. 124,872.

To all whom it may concern: I

Be it known that I, HENRY W. SCHMIDT, a citizen of the United States,residing at the borough of Manhattan, New York city, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in Aeronautical Apparatus, of which the following is aspecification, reference being had therein to the accompanying drawing.

y invention relates to improvements in aeronautical apparatus and moreparticu-' larly has reference to means in combination with eitherheavier-'than-air or lighter-thaw air craft for producing motive im ulsethereupon in practically any desired irection as hereinafter more fully,set forth.

In the accompanying drawings I have illustrated in Figure 1, in sideelevation an application of my invention as applied to a suitable formof air craft. Fig! 2, is an end view of the same looking from right toleft at Fig. 1 and Fig. 3 is a .plan View looking downwardly uponFig. 1. i

4 is .a suitable boat structure provided with a suitable motor such as 5and windows or port holes such as 6, as well as suitable pilot wheelsindicated by the reference character 8 and other proper equipment. 10 isa suitable formof aeroplane superstructure mounted above the' same. Atthe front of the machine indicated by the reference character 11, asuit-able propeller, such as 12, may be driven to draw air into thepassage 13, the same being expelled through the conelike rearwardportion 14, which terminates in a transverse cylindrical portion 15 uponwhich is preferably rotatably mounted another portion terminating in thehollow surface 17, thus permitting the surface 17 to move upwardly anddownwardly looking at Fig. 1, the ends of the cylindri- .cal portions15-16 being closed and the end of the tail surface 17 being opened at 18to allow for the discharge of ward-1y by the propeller 12.

19 is another hollow flat surface .open at the end 20, and serving as arudder the same being rotatabl connected beneath the ele- 7 as shown andbeing movable vator surface 1 therewith and provided with an inwardlyprojecting deflector 21 which is adapted to cause part of the air whichpasses outwardly from the cone 14 to be air driven reardeflected throughrudder 19 as well as the-elevator 17. The

one of the pilot wheels'8. .A 21 is also secured to the other end of thecable 23 so that by operating the pilot wheel the elevator'l may beraised or lowered as desired. The rudder 19 is also suitably connectedby a cable 'to another of the pilot wheels 8, as shown, and suitablesliding connection is provided between the'elevator 17 and rudder 19 asshown at 24.

25 indicates suitable air vents or discharging members rotatably mountedat 26 so as to allow air to discharge therefrom and to strike upwardlybeneath the'planes 10 or in any other direction according to theposition in which the air outlets 25 may be rotated, each of these airvents or outlets being connected to cone shaped passages 27 in thelarger ends of which are mounted suitable fans, or propellers such as 28which draw the air from the passage 29 when rotated by suitablesprockets and chains as shown. In the position shown in Fig. 1

over the pulley 24 and down-- Patented Jan. '7, 1919.

the air outlets 25 are directed. aftv eachfl succeeding one above orbelow the other, so as to allow the air to react upon the atmosphere insuch a manner as to drive the craft forwardly, the air being drawn intothe passage 29 from the front of the machine at 11. .B'y operating oneof the pilot wheels 8 these air outlets may be simultaneously rota'teddownwardly when alighting to reduce the shock of landing.

From the foregoing, it will be apparent that in addition to the part 19providing a rudder surface, the action of the same is augmented by.virtue of the-reaction of the air emitted from the end thereof and 'itwill also be observed that the same applies to the elevator'17,and'ofcourse, it will be understood that a suitable gas bag or other auxiliaryattachments may be provided if d'esirable'for lifting the machine in anywell known manner. In fact various modifications may be made in theconstruction and arrangement of parts without departing' from the spiritof theinvention as claimed.

- I claim:

1.. In an apparatus of the class described,

a. horizontal and a vertical rujdder therefor,

and means in combination therewith for drawing air from the front ofsaid machine and discharging the same through said rudders out of thetrailing edge thereof. 5 2. In an apparatus of the class described,

an air supporting surface, means for drawing in air beneath the front ofthe same and for discharging said air beneath opposite sides of saidsurface and at an adjustable H) angle thereto. hollow vertical andhorizontal rudders at the stern thereof, and means for discharging someof saidair through the trailingends of said rudders.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses; 15
